Methodology · updated November 10, 2026

How we verify a price

A number goes on Wellness Vision only after it has been opened in the source we cite — the exact entry, its date, its pack size. Where we calculate something ourselves, we say so and show the formula. This page describes the steps, and what we do when a step fails.

1. The order of sources

  1. Official price lists first. For medicines: the US pharmacy acquisition cost survey (CMS NADAC), Medicare’s negotiated prices (CMS), the NHS dictionary of medicines and Drug Tariff (UK), the French public medicines database, the German statutory price ceilings (Festbetrag list), the Swiss Spezialitätenliste, the Austrian Erstattungskodex and the Dutch Medicijnkosten.nl. For procedures: official tariffs where they exist, such as Medicare fee schedules or the Turkish Ministry of Health tariff.
  2. Then laws, health-policy research and peer-reviewed journals — the specific document, not an organisation’s homepage.
  3. A maker’s statement only for the maker’s own price — for example a list price published on the drug’s US website or in a state price disclosure, always with its date.
  4. Market estimates, labelled. Many treatments abroad have no official price. There we show a range and call it a market estimate.

We do not use clinic or hospital websites, medical-travel agencies, price aggregators, Forbes Health, Healthline, WebMD or Wikipedia as a source of fact. The full list is on Data Sources.

2. Every figure is opened at its source

  • The entry, not the summary. We open the price list or document itself and read the entry: product, strength, pack size, price type and the date the source gives.
  • A dated record. For every drug-price page published since November 6, 2026, a verification record lists each figure, the source entry it comes from and the date it was retrieved. We are extending this to older pages as we re-check them.
  • A script checks the page against the record. On those pages, every number shown on the finished page is compared with the record before publication. A number that is not in the record stops the release until it is explained; only chart axis labels and the titles of linked articles are exempt.
  • Research help is a lead, not a source. We use AI tools to search and draft. Anything they find is treated as a lead and is published only after the primary source has been opened.

3. Our calculations are marked

Any figure that does not appear in a source — a currency conversion, a 30-day cost, a percentage or a multiple — is labelled our calculation and shown with its formula, for example “$66 ÷ $346”. We do not use fractions such as “a fifth” without the formula behind them.

  • Currencies: European Central Bank reference rates of a stated day.
  • Packs to 30 days: pack price ÷ pack size × the number of units 30 days need at the label dose — for example a pack of 28 scaled to 30 tablets.
  • Per-unit prices: where a source prices a single tablet or capsule, we keep its decimals in the table and multiply only in the column marked as our calculation.
  • Rounding: half up, to whole dollars in headlines and charts.

4. Different prices, labelled

A “price” can mean very different things, and we name which one we show:

  • List price (US wholesale acquisition cost) — the maker’s price before discounts and rebates.
  • Negotiated price — the price Medicare negotiated under the Inflation Reduction Act, in force from the date CMS gives.
  • Pharmacy acquisition cost (NADAC) — what US pharmacies pay on average.
  • Official European prices — public or retail prices, social-insurance prices excluding VAT, the NHS price, or the German statutory ceiling (Festbetrag), each as its source defines it.
  • What patients pay — shown separately, because co-payments, deductibles and insurance rules differ from the price itself.

5. The same amount of medicine

We compare the same dose for the same period: the label dose from the official prescribing information, usually 30 days. Medicines taken in cycles — such as 21 days on and 7 days off — are compared per cycle. Where strengths cost the same, we say so; where they do not, we name the strength we show.

6. What we do not do

  • We do not work around access restrictions. If an official or maker website blocks access, we do not bypass it; we say that the figure could not be checked and use another official source or none.
  • We do not invent totals. Official tariff lines are not added up into a package price.
  • We do not name, rank or recommend clinics, pharmacies or suppliers, and we give no medical advice — see the medical disclaimer.

7. English and German

German pages are checked number by number against the English page, and their language is checked automatically. Differences are deliberate: German pages put Germany, Austria and Switzerland first and add German co-payment rules.

8. Dates and updates

Every page shows when it was published and last updated, and every source line names the date of its data. When an official source publishes a new edition, we re-check the pages that use it; changes to official prices are listed on Price changes, and our compiled official prices are available as open data.

9. When we get it wrong

Email [email protected] with the page and the source. We review within 7 business days, correct the page, change its “Updated” date and record the change with its date on Corrections.
